BD Diesel 19-23 Chevrolet Silverado / GMC Sierra 1500 8L90 Cooler Bypass Delete

Doing a transmission service on your 2019-2023 Chevrolet Silverado 1500 or GMC Sierra 1500? If you're concerned about transmission temperatures, especially under load, this cooler bypass delete kit from BD Diesel is worth a look. The factory bypass valve can get jammed with debris, forcing the transmission fluid to recirculate instead of going through the cooler. This can lead to higher temps and eventually damage your transmission.

This kit replaces that factory valve with a solid tube, ensuring that 100 percent of your transmission fluid always flows through the cooler. By keeping the fluid moving through the cooler constantly, you help keep your transmission temperatures as low as possible, which is crucial for longevity, especially if you tow or haul heavy loads. It comes with all the new seals you'll need for installation, plus a magnetic service plug, which can help you keep an eye on any potential metal wear in your transmission fluid.
